that formula to get the spear.Heck one is enough; 4 is too much in my view and unnecessary.

I never got the spear originally because I opened the forbidden chests.I do agree Square was punative with the way they did the chests in this game.

I stopped playing as I found the game deficient, plus with all the criticism I received on other forums for expressing my views about the game I stopped.
I do occasionally feel an urge to pick it up again depsite all the adversity I went through over it.

Getting the spear would be nice and I might try it again at some point.
